TRAIN-SIGNAL SYSTEM.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed January 80, 1914. Serial No. 815,575.

To all whom it may concern:

Be it known that I, WILLIAM ERNEST BENN, a subject of the King ofEngland, and a resident of McAdam Junction, 1n the county of York andthe Province of New Brunswick, Canada, (whose post-oliice address isMcAdam Junction, New Brunswick,) have invented and discovered certainnew and useful Improvements in Train- Signal Systems, of which thefollowing is .t specification.

The invention to be hereinafter described relates to train signalsystems.

In order to more clearly disclose the construction, operation and use ofthe invention, reference should be had to the accompanying drawingsforming part of the present application.

Throughout the several figures of the drawings like reference charactersdesignate the same parts.

In the drawings :-Figure 1 is a longltudinal cross section through anair brake pipe, showing the wiring; Fig. 2 is a cross section on line 22of Fig. 1; and Fig. 3 is a diagrammatic view of the system, complete.

The main objects of the system are to pro vide a simple, elficient,economical, compact and durable signaling system which may besubstituted for the present air signaling system without the manyinconveniences and the considerable expense of air signaling system.

Referring to the drawings in detail, 1 indicates the upper and 2 thelower jaw of an air brake hose coupling. The upper jaw is castseparately and secured in place by a clamp 3. Between the jaws is seateda layer of insulation 4. Within the hose are arranged the two wires 5 ofan electric signal system, the positive wire being connected to one jawand the negative to the other jaw. Thus, when all the couplings of atrain have been made, the circuit will be complete from end to end,including the necessary batteries and a signal bell in the engine cab.At various points in the system a push button or buttons may be placedfor signaling pur poses. Where the air brake hose enters the storagecylinders, the wires are brought out and crossed through a block 6, inany well known manner.

Gupta 0! this patent may be obtained for It is thought that theconstruction, operation and use of the invention will be clear from thepreceding detailed description.

Changes may be made in the construction, arrangement, and disposition ofthe several parts of the invention without in any way departing from thefield and scope of the same, and it is meant to include all such withinthis application wherein only a preferred form has been disclosed.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In combination, air brake hose sections,separate upper and lower coupling jaws connected to each of saidsections, insulation be tween the upper and lower jaws of each section,electric conductors mounted within said hose sections and connected tosaid jaws, a signaling device included in the circuit of saidconductors, and means for effectually connecting the positive and thenegative side of the circuit.

In combination, air brake hose sections, separate upper and lowercoupling jaws connected to each of said sections, insulation between theupper and lower jaws of each section, and electric conductors mountedwithin said hose sections and connected to said jaws.

3. In combination, air brake hose sections, separate upper and lowercoupling jaws connected to each of said sections, insulation between theupper and lower jaws of each section, electric conductors mounted withinsaid hose sections and connected to said jaws, and a signaling deviceincluded in the circuit of said conductors.

4. In combination, air brake hose sections having coupling members withseparate upper and lower coupling jaws connected to each of saidsections, insulation between the upper and lower jaws of each section,electric conductors connected to said jaws, a signaling device includedin the circuit of said conductors, and means for closing the circuit,substantially as set forth.
